Two common methods are the Wohlwill process and the Miller process.
The most effective methods for extracting and refining a pool of gold include mining, crushing, and processing the ore to extract the gold. This is typically done through techniques such as cyanidation, smelting, and refining processes like electrolysis or chemical leaching.

When gold is refining, it is called smelting. Smelting involves heating the gold to a high temperature to separate it from impurities and other metals. The purified gold is then typically cast into bars or ingots for further processing.
You can find more information about the process of refining gold online at the Precious Metal Refining Info website. You can also watch a video about the process at the YouTube video streaming website.
Do you mean pure gold, or the process of refining gold? no to the first yes to the second
A furnace for refining gold is used to melt and separate impurities from gold ore, resulting in pure gold. This process involves heating the gold ore to high temperatures to melt it, while impurities separate and are removed as slag. The pure gold is then cast into bars or other forms for further processing.
Since pure gold is incredibly soft, it's alloyed with other metals like silver and nickel in order to make it stronger. The amount of silver or any other alloy in gold varies since different sources use different methods and alloys when refining it.
Well. if it is 24k it doesn't need refining. But if it is 18k or 22k if you have 18k acid or 22k acid used the test and trust yourself first and used magnet test. Then you can depending what kind of refining are you dealing with; and you can trust. In one ounce 18k gold metal you can loose the mixed alloys; but you can never loose the gold metal. In the Refining you can loose the wholesale and the retail value if it is a jewelry and you sale to them. If you deal with Professional people that told you the truth you don't have any loss...

One highly recommended book on refining precious metals is "Refining Precious Metal Wastes" by C.M. Hoke. It provides detailed information on various refining techniques, processes, and equipment needed for refining gold, silver, platinum, and other precious metals. It is often considered a comprehensive guide for individuals and businesses involved in precious metal refining.
